- binder solutions or dispersions or melt binder used to consolidate the fleeces and for connecting the nonwoven fabric with the reinforcing yarns.
- melt binder used to consolidate the fleeces and for connecting the nonwoven fabric with the reinforcing yarns.
- melt binder is either in the form of separate Binding filaments added to the nonwoven or at least one Part of the filaments of the reinforcement yarns consists of bi-component filaments, where the one component as Melt binder works.
- the known nonwoven webs it has been shown that either the delamination properties not fully satisfied yet or that the breaking strength is not reached in height, like in itself due to the amount of reinforcing yarns used is to be expected.
- the object of the present invention is a nonwoven web to make available of the type mentioned at the beginning, where delamination is also practical in smaller areas can no longer be determined, and that at a low level Grammage an exceptionally high stability having.
- a filament reinforced Nonwoven web which is flocked into the nonwoven web integrated, parallel running reinforcement yarns reinforced is, the filaments forming the fleece A to the Crossing points with filaments B of the reinforcing yarns and at least in places over the filaments B.
- a binder are connected to each other, which nonwoven web is characterized in that the filaments A des Fleece among themselves at their crossing points same binder are connected.
- the reinforcing yarns are preferred at least predominantly in the longitudinal direction of the Nonwoven web arranged.
- Reinforcement yarns should be present, which is then beneficial is that there are at least two droves in the nonwoven web cross integrated parallel reinforcement yarns. It has proven particularly useful here if at least one share predominantly in the longitudinal direction and another coulter at least predominantly arranged in the transverse direction of the fleece is.
- the arrangement of crossed reinforcing yarns leads to a particularly good dimensional stability of the nonwoven web according to the invention. It also shows hardly any ripple on.
- the reinforcement yarns can be arranged lengthways and crossways the number of reinforcing yarns per unit length, the strength and the module in the longitudinal and transverse directions are different or be set to the same height.
- Arrangement of crossed reinforcing yarns can also the tear strength of the nonwoven web significantly improved become.
- the nonwoven web according to the invention has a nonwoven weight between 50 and 300 g / m 2 .
- a nonwoven web in which the binder for connecting the Filaments of the nonwoven with each other, the connection of the Filaments of the nonwoven with the filaments of the reinforcing yarns and the connection of the filaments of the reinforcing yarns serving with each other is in EP-A-0 506 051 not described. It must be looked at all the more surprisingly be that this measure delamination also in smaller areas is practically no longer observed and at the same time the stability is increased.
- the nonwoven web according to the invention is particularly distinguished characterized in that the binder is a melt binder, whose melting temperature is lower than the melting temperature of filaments A and B of the nonwoven web.
- the inventive Nonwoven web the filaments A of the nonwoven and the filaments B the reinforcing yarns from a similar, in particular consist of the same polymer. It is an advantage if for the filaments A of the nonwoven and / or for the Filaments B of reinforcing yarns bi-component filaments be used.
- the task set according to the invention succeeds excellently, if in the nonwoven web the filaments A of the nonwoven and the filaments B of the reinforcing yarns made of bi-component filaments exist, the one component of Bi-component filament is the melt binder. Especially It is favorable here if the bi-component filaments Core-sheath filaments are where the sheath is the melt binder is.
- the core component of the core-sheath filaments are suitable practically all meltable polymers, such as Polyethylene terephthalate, polypropylene, polyethylene, Polyamide, polyurethane or PVC.
- the jacket component the same polymers are suitable, but towards them ensure that the jacket component has a melting point which is at least 10 ° C lower than that Melting point of the core component.
- a particularly cheap one Polymer selection for the core-sheath filaments of the nonwoven web according to the invention results when polyester as core component and polyamide, especially polyamide 6, is used as a jacket component. This is preferred the sheath proportion in volume percent of the core-sheath filaments between 5% and 40%, in particular between 10% and 35%.
- the posed Task solved particularly well when the distance is closer Reinforcement yarns between 2 and 30 mm, especially between 4 and 15 mm.
- the nonwoven web according to the invention is still distinguished through a number of particularly favorable properties, the suitability of this nonwoven sheet as an insert for bitumen sheets or as a roofing membrane but also as Tufting reason for carpets makes it clear.
- the modulus at 5% elongation is the one according to the invention
- Nonwoven web preferred at least 170 N, in particular at least 190 N per 5 cm and per 100 g fleece weight.
- the elongation at break can be found in the nonwoven web of the invention adjust well by using appropriate filaments combined with a binder ensuring the elongation at break become. However, the elongation at break can also be adjusted by suitable Selection of filaments A and / or filaments B accordingly can be set. The elongation at break is preferred between 15% and 70%. For bitumen sheeting, the Elongation at break slightly to 15% to 50% and for tufting base Set 30% to 65%.
- the breaking strength is preferably between 300 and 600 N, in particular between 400 to 550 N per 5 cm and per 100 g, while the tear resistance values from 100 to 300 N, preferably from 130 to 250 N per 100 g.
- the modulus, the elongation at break and the breaking strength are on a 5 cm wide strip where the reinforcement yarns run in the longitudinal direction at a pulling speed of 20 cm / min and a temperature of 21 ° C. (DIN 533 857).
- the module can be in measured in every direction in which the reinforcing yarns run become.
- the tear resistance is on a 5 cm wide Strip, in which the reinforcing yarns in the transverse direction run at a drawing speed of 10 cm / min and a temperature of 21 ° C determined (DIN 53 363).
- the tear resistance of reinforcing yarns that cross over each transverse to the direction of the reinforcing yarns be measured.
- the nonwoven web according to the invention also has a excellent mechanical stability at high temperature on.
- the mechanical stability at high temperature in The longitudinal and transverse directions are determined as follows: On a strip 60 cm long and 10 cm wide centered a 10 cm long and 8 cm wide rectangle, the longer side being arranged in the longitudinal direction is. The strip is attached between two clamps in such a way that the free length between the clamps is about 25 cm is. After a 10 minute treatment in one Oven heated to 180 ° C under a load of 57 N. the dimensions of the recorded rectangle are measured. The difference to the original length or width of the recorded rectangle is in proportion to the original Length or width set and specified in%.
- the nonwoven web according to the invention preferably has a stability S 1 in the longitudinal direction, wherein 4.2 - 0.015 * G ⁇ S 1 > 0 and where G is the total weight of the nonwoven web in g / m 2 .
- a transverse stability being - 4.8 + 0.017 * G ⁇ S q ⁇ 0 and where G is the total weight of the nonwoven web in g / m 2 , is another preferred embodiment of the nonwoven web according to the invention.
- Bicomponent filaments of the core-shell type in which the core consists of polyethylene terephthalate and the shell made of polyamide 6, are produced in a known manner in such a way that they have a core fraction of 73 vol% and a shell fraction of 27 vol% exhibit.
- the core-sheath filaments are then drawn and then have a breaking strength of 36 cN / tex, an elongation at break of 64% and a titer of 1,650 dtex.
- the core-sheath filaments are deposited in a known manner on a moving steel fabric belt, the feed speed of the core-sheath filaments 358 m / min (example 1) or 376 m / min (example 2) and the speed of the moved Steel mesh belt is 20 m / min (example 1) or 13 m / min (example 2).
- 143 m 2 yarns per meter are placed on the core-sheath filaments, which are evenly laid in a tangle, at the same speed as the moving steel fabric belt, each yarn consisting of 110 core-sheath filaments of the same type with which the first tangle layer was produced.
- a further layer of core-sheath filaments of the same type is fed onto the structure that has now arisen in the same way as the first layer, as a result of which they are arranged in a tangled position on the first tangled layer and the yarns which are now parallel.
- Hot air is then blown onto the resulting structure at a temperature of 224 ° C. through the structure and the steel mesh belt.
- this thermal treatment which is followed by cooling, the filament-reinforced nonwoven web that has now formed is consolidated.
